Authorities booked Patrick Pittman, 33, on several counts including second-degree murder, second-degree kidnapping, obstruction of justice and illegal firearm possession as a felon. Pittman was identified as the second victim in the shooting.

Jefferson Parish deputies responded to a report of gunshots on North Laurel Street and found 28-year-old Leonard White suffering from multiple gunshot wounds. White was pronounced dead at the scene.

According to a news release issued Sunday night, Jefferson Parish investigators learned Pittman allegedly shot White after a fight at a block party. Having opened fire, authorities said Pittman ran from the scene and was wounded during a different gun battle that the sheriff's office said is still under investigation.

Wounded, Pittman then entered a vehicle of an "uninvolved party" and demanded at gunpoint to be driven to a hospital, the sheriff's office said. Authorities said Pittman was arrested following his release from a hospital Sunday evening.

The sheriff's office noted Pittman "has an extensive prior arrest history that includes narcotics offenses and crimes of violence." Court records show Pittman has a number of marijuana possession convictions dating back to 2001 and in 2005 was charged with first-degree murder. That charge was eventually dropped.

Anyone with information regarding this double shooting is asked to contact JPSO's Homicide Section at 504-364-5300 or to call Crimestoppers.
